Product Details

Dayton Audio PT2C-8 Planar Tweeter

Many audiophiles praise the Dayton Audio PT2C-8 ribbon tweeter's excellent clarity, transparency, and imaging. The key to this remarkable performance is the almost weightless ribbon element: a Kapton film membrane etched with a pattern of aluminum conductors and placed precisely between two rows of neodymium magnets. The result is an immediate response to any transient impulse found in the original signal.

The Dayton Audio PT2's ability to deliver musical detail is clearly amazing. The tweeter's large membrane and radiating area provide higher power handling and a substantially lower cut off frequency. This membrane is thermally attached to a cast aluminum plate that facilitates cooling and dramatically increases dynamic range. The flared waveguide's wide horizontal dispersion projects an excellent off axis response. At the same time, vertical dispersion is limited, which reduces distracting floor and ceiling reflections. Perfect for line array applications. The recommended second order crossover cut-off frequency is 3 kHz or higher, although the crossover point can be lowered to 2,500 Hz if a 3rd order crossover is used.

Dayton Audio PT2C-8 Planar Tweeter
Dayton Audio PT2C-8 Planar Tweeter is rated 4.6 out of 5 by 40.
Rated 4 out of 5 by from Short listening time, but jaw dropping sound.I built up a 500w boombox and placed this tweeter front and center. I am very fickle when it comes to tweeters and tend toward tuning the highs down a bit so they don't become irritating and fatiguing. I was Very Very pleased to have this guy handling the highs! Incredibly smooth, very nice off axis response and great authoritative control over the highs.Cymbals, tambourines, hand claps, 'T's and 'S's all came through with great clarity and control. Current the speaker is in the hands of a professional sound twiddler, so i'll have a great feedback point shortly.

Rated 5 out of 5 by from Clean, Clear, and mighty attractive.Bought these with the hope to have crisp clean highs without the extreme harsh detail of a small round dome tweeter. These were the high's to a 3-way speaker tower I built, absolutely what I was looking for. The clarity, detail and depth is astonishing. I have them crossed over at 5000hz (12db/2nd order) plays a perfect match to the 4 inch reference mid-woofer.

Rated 4 out of 5 by from Sweet and SmoothI have these paired with 2 Celestion 5" full rangers and an Emminence Beta 15 in an simple open baffle arrangement and all I can say is wow. I have gone back and forth between 5k second order and 3500 3rd order and settled on the 3500. I was waiting for all the components to break in before I wrote a review. At first I thought they were a little forward, but that was actually the Celestions and an L-pad took care of that. These seem to blend perfectly with this set-up. The staging is very wide and the image produced is awesome such that you can pick out exactly where the instruments are on the stage. Vocals being rock solid center stage. I have to say that these Planar Tweets are very revealing, open and can you say dynamic.. I was playing some Coltrane at moderate levels and the wife came into the room thinking someone was actually in the room playing the saxophone. I think that's the best thing you can say about a speaker set-up is that it's true to the recording.I've since blown the dust off the record collection and have been rediscovering music.One last thing. Each open baffle arrangement can see over 350 watts continuous from my Parasound HCA-3500 and possibly 0ver 500 watts depending on the ohm load. I've turned up to what most would consider to be very loud for a couple hours at a time and haven't had any issues.Great Job PE. Another successful speaker at a solid price especially when compared to "name brand" products of similar sound quality.

Rated 2 out of 5 by from No no, Dayton.I'm going to assume that whoever has been reviewing this item so far can't have tested it properly... At all. The specs are totally off. It can't handle anything close to 80 watts before it gets smoked. I bought some to use in a line array config after asking a question or two even here on the site. Now, I've got two dead and Im thinking what to do with d rest... Its probably OK for Home theatre though.

Rated 5 out of 5 by from well builtI got these Dayton planners, Dayton 2" mid domes, Dayton 8" designer series speakers, and the100 watt Dayton 3-way crossover for my first DIY project . When I received the order ,I though wow!! These are some well built speakers . I build a .8 cu FT with a 2.5" port 1 " . Installed these speakers, an the x-over . Running them off a 80 watt rms x 5 pioneer VSX-822 the speakers were a little rough sounding at first , but after I reversed the polarity on the mid an added an l-pad on the mid to turn it down a little bit , these tweeters really sound awesome. very crisp but not harsh at all . really clear sounding and can be cranked up LOUD an still sound great. They sound best at ear level .This project with all the Dayton products work great together an sound awesome .So if you r planning a project ,you wont be disappointed with Dayton products, or the prices.

Rated 5 out of 5 by from Clean reproductionI bought it to use it as a linesource to compliment my ESS Heil AMT mid/tweeters. Blends well on a linesource configuration with other ribbon drivers. It has similarities to carver sunfire loudspeaker ribbons used on their smaller speaker designs. You need to match this with quality crossovers in order to produce it's maximum efficiency. For the price, it is a bargain and highly recommended for small to large linesource DIY loudspeaker projects. Well designed as a replacement as well. This is much more quality design compared to other similar designs. Highly recommended!

I have Pt2 Planar tweeters from you and do not see + or - markings anywhere. From the top, where the terminals are, looking at the back, where the terminals are; which terminal is +?

Asked by: cjm6274
The wider of the two terminals will be positive. This will be the left side terminal as oriented in the rear picture online.

Is this item the same as 6" Cinema Ribbon in the  Sunfire CRM-2? Bob Carver mentioned Sunfire negotiated production rights for the first two years after which the item would be sold elsewhere, specifically Parts Express.

Asked by: godzilla
Answering my own question: A very likely yes, Comparing the photos to the CRM-2 they look identical.

Does anyone have any thoughts about using four of these in a line source config with two 10" acoustic suspension woofers crossed over at 5000hz.  It seems that would create a subdued midrange, which is what I like. 

Asked by: 1957Teddy
These will work well for a line array type application with that crossover point, although without knowing anything about the woofers it is impossible to say how it will sound. Usually crossing a 10" any higher than about 1500 Hz is a bad idea for off axis response.

Thinking of using either 4 of the dome silkies or 2 of the planars (per ch.) for a line array project. Any thoughts?

Asked by: Mike8
planars are typically a little better suited to line array applications as they behave like lines by nature so using multiples just extends that. Domes need to be spaced as close together as possible and still are limited by the top end by the distance you can space the drivers.
